Big blue has a USB port on the PCB directly, any chance we get something for Big blue?  Thanks!

I wanted to say thank you very much for this mod. I've got the MK countercade.  I have two questions about it that I can't find an answer to:

1. The standard volume output is deafening and I can't figure out how to adjust the volume. my volume nob does nothing. How do I adjust it? 

2. MAME doesn't show up on the main menu of emulators. I must have installed the roms wrong or there is an issue I'm not figuring out. my Genesis rom shows up fine but no MAME. How do I fix this?

I just went into settings on the main Batocera screen and under sounds, turn off front-end music. After that I was still able to control game volume with the volume controls.

You can adjust volume from within games, you will not see the volume bar appear you just press the button and you will hear the volume go down.

Update: I figured out my problem with MAME. The hard part is finding roms that actually work. I’m aware of them having to be of the version of MAME

thank you for these mods, i just did my nba jam and had a couple of quick questions if i may...

1. everything is so slow.  games play fine but navigating menus is painful.  anything i can do to make it a bit snappier?

2. does the nba jam board have the capacity for additional inputs?  i'd like to create a new panel with more buttons.

thanks again so very very much!
